On Legendrian representatives of non-fibered knots

Zhenkun Li, Shunyu Wan

We show that in $(S^{3}, ξ_{s t d})$ if $K$ is a non-trivial knot that realizes the three-dimensional Thurston-Bennequin bound (i.e. $K$ has a Legendrian representative $Λ$ with $tb(Λ)-…

2-torsion in instanton Floer homology

Zhenkun Li, Fan Ye

This paper studies the existence of $2$ -torsion in instanton Floer homology with $Z$ coefficients for closed $3$ -manifolds and singular knots. First, we show that the non-…
